<h3 id="rationale">Rationale:</h3>
<p>ShellCheck has noticed that you're using a <code>printf</code> with
multiple arguments, but where the first argument has no <code>%s</code>
or equivalent variable placeholders.</p>
<p><code>echo</code> accepts zero or more strings to write, e.g.
<code>echo hello world</code>.</p>
<p><code>printf</code> instead accepts one pattern/template with zero or
more <code>%s</code>-style placeholders, and one argument for each
placeholder.</p>
<p>Rewrite your command using the right semantics, otherwise all
arguments after the first one will be ignored:</p>
<pre><code>$ printf hello world\\n
hello

$ printf &quot;hello world\n&quot;
hello world

$ printf &quot;hello %s\n&quot; &quot;world&quot;
hello world</code></pre>
<h3 id="exceptions">Exceptions:</h3>
<p>If you wanted a no-op, use <code>:</code> instead.</p>
<div class="sourceCode" id="cb4"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb4-1"><a href="SC2182.html#cb4-1" aria-hidden="true" tabindex="-1"></a><span class="bu">:</span> <span class="va">${place</span><span class="op">=</span>world<span class="va">}</span></span></code></pre></div>
